Ask a chatbot, or ask a specialist.
A general chatbot answers from whatever it read online, then starts over next time. Murph is built for health: grounded in current research, it reads your own data, remembers your history, and acts on it, across sleep, food, training, sauna, and recovery.
Each skill starts with the research, not a stray article. We read it, then build the skill from it.
Not every study holds up. Murph leans on the strong ones and flags when the evidence is thin.
When new research comes out, the skill is updated. It is not stuck on what an AI read years ago.
Each skill is a public playbook. Read exactly what Murph knows, and the studies behind it.
